For decades, the .NET ecosystem was inextricably linked with SQL Server. Today, the landscape has shifted. As .NET 10 and containerization become the standard, PostgreSQL has emerged as the definitive choice for modern distributed systems. But at enterprise scale, treating PostgreSQL as a "database-agnostic" black box is a recipe for failure.
PostgreSQL for the Senior .NET Architect is not an introductory guide. It is a deep-dive manual for the individual responsible for the performance, scalability, and integrity of mission-critical systems.
Through the lens of Apex —a high-scale multi-tenant fintech SaaS platform handling 5M+ users and 10,000+ transactions per second—you will explore:
* Internal Mechanics: MVCC, WAL, and Buffer Management internals and how they dictate your .NET application’s behavior.
* EF Core at Scale: Advanced Npgsql tuning, compiled queries, and avoiding the performance traps that sink large-scale projects.
* Advanced Data Modeling: Leveraging JSONB, Partitioning, and GIN/BRIN indexing for complex enterprise workloads.
* Distributed Patterns: Implementing the Outbox pattern, Sagas, and Idempotency with PostgreSQL’s unique feature set.
* Production Readiness: High Availability (Patroni), Kubernetes operators, and zero-downtime migration strategies.
Verified by a rigorous "Enterprise-Level Strict Mode" technical review, this book provides the strategic insights needed to transition from "making it work" to "architecting for 99.99%."
